Abstract

A method and apparatus for wireless control of audio and video recording device operations via selections from an Electronic Programming Guide (EPG) is disclosed. A digital satellite receiving system receives and processes a digital data stream containing television programming information, EPG information, and a list of video cassette recorders (VCRs) and corresponding infrared (IR) codes used to control the listed models of VCRs contained in the list. The VCR list, corresponding IR codes, and EPG information are stored in memory. A user may select a specific model VCR from the list displayed on a viewing screen and the corresponding codes are stored in a memory. The received EPG information may also be displayed on a viewing screen. The user may select for recording an event listing in the EPG, and this selection is also stored in nonvolatile memory. EPG information is repeatedly transmitted in the digital data stream. As scheduling information for the selected event changes the receiving system adjusts the control of the VCR so that the selected event will be recorded in its entirety. The digital receiving system uses the codes saved in nonvolatile memory to generate and transmit an IR signal to the VCR to start recording when the EPG determines the selected event begins. The EPG and selected program are monitored during recording. At the end of the program, a transmitted IR signal terminates the recording operation. Additionally, the receiving system may receive new IR codes via the data stream so new recording devices may be used as they are made available. High powered IR energy signals are broadcasted, in the local area to control the operation of the associated VCR or other remote controlled device without necessity of the IR generator being in the line of sight of the VCR.
